When internal load-bearing structural elements fail, a building will collapse into itself and exterior walls are pulled into the falling structure. This scenario may be caused by a variety of factors, including awareness of construction area standards, checking the foundation, avoiding major alterations, building earthquake-proof construction, and seeking help from a professional structural engineer.
Strategic links save buildings from total collapse by incorporating components that can control the propagation of failure by isolating parts of the structure. A four-phase collapse rescue operational plan, effective use of outside resources, proper shoring techniques, and specialized rescue tools and training are essential for preventing structural collapse.
The GSA publication provides a threat independent method to reduce the potential for progressive collapse. Practice Drop Cover and Hold during shaking and evacuate to safety outside the building when the shaking stops. To ensure safety, activate search and rescue teams, often highly trained volunteers. Learn about the causes, types, and preventive measures for building collapse and stay informed to protect structures and ensure safety.
Collapse rescue shoring, such as box cribbing and the larger vertical shoring system, provides temporary support of a damaged structure. Continuous top and bottom reinforcement properly anchored into columns prevents “rip-out” after shear failure has occurred, reducing the likelihood of collapse.
For emergency situations, form alternative evacuation routes to elevators, escape stairways, and other horizontal exits without travel through rooms that are not earthquake-proof. By following these guidelines, you can help prevent the collapse of buildings and ensure the safety of your employees and the public.

At first, just a few bricks fall from the building. Then minutes later, the entire facade crumbles.
How to prevent collapsing?
A collapse is when someone falls down for no obvious reason, often due to fainting, low blood pressure, or other serious factors. It can be a medical emergency and can be prevented by changing position, standing up slowly, staying hydrated, eating well, getting fresh air, and avoiding triggers. Symptoms include difficulty breathing, difficulty concentrating, and difficulty breathing. When someone collapses, they should seek medical attention, and the diagnosis and treatment process vary depending on the cause. Preventing a collapse involves changing position, standing up slowly, staying hydrated, eating well, getting fresh air, and avoiding triggers.
How to survive a collapsing house?
During a building collapse or explosion, cover your nose and mouth, minimize movement to avoid dust inhalation, and use a flashlight to signal your location to rescuers. If you suspect structural damage, gas leak, or sabotage, call 911 and exit the building as soon as possible. If you are outside, move away as quickly as possible. Remember to cover your nose and mouth, move around minimally, and use a flashlight to signal your location.
Where is the safest place to be during a building collapse?
In order to ensure personal safety during a natural disaster, it is essential to seek immediate shelter in a protected area, such as a doorway or under a desk. It is also crucial to avoid windows, shelves, and heavy equipment, and to move away from buildings and utility poles. Furthermore, it is advisable to park in a secure location, away from power lines and trees.
How do you stop a wall from collapsing?
When building a retaining wall, it’s crucial to pack the soil underneath it to prevent future settlement and potential wall cracking or collapse. Experts at Design Everest suggest taking quick action to avoid these issues. Another precaution is to optimize the wall’s breadth to strengthen its front, as the extension of the footing toe can decrease soil bearing pressure. By doing so, you can prevent your wall from falling and work smartly.
What floor is safest in an earthquake?
During an earthquake, it is crucial to stay indoors and follow the following safety measures:
Understand the earthquake’s tremors and construction principles. Tall buildings, such as high-rise apartments, are designed to withstand lateral loads from earthquake impacts. Residents of the top floor of a high-rise building are safer than those in the open street.
Be calm during an earthquake. Patience is essential to reduce fear-inducing hormones and give courage to face seismic activity. Stay indoors and stay put, not running in desperation.
Protect yourself by not standing close to windows or doors, bookcases, hanging objects, or heavy furniture that could collapse. Lock the wheels of wheelchairs and ensure head and neck safety using pillow or soft-thick materials.
Switch off gas cylinders, stoves, and electricity-running appliances until the earthquake stops.
Do not stand and run, as there is a risk of falling on the ground due to the building’s sway. Instead, drop on the floor with knees and hands on the ground and sit under a sturdy table.
Do not use an elevator during an earthquake. Stay indoors and follow the preventive measures outlined above.
How do people survive collapsing buildings?
To prepare for a building explosion, cover your nose and mouth, move minimally, use a flashlight to signal your location, tap on a pipe or wall, and use a whistle if you have one. Shout only as a last resort to avoid inhaling dangerous dust. Fires often occur after a building explosion, so learn more about fires. Follow emergency responders’ instructions and do not try to re-enter a building or debris field to look for personal property.

What keeps a building from falling?
The structural engineers responsible for the design of buildings are tasked with ensuring the stability and integrity of the foundations and wall constructions, which must be capable of supporting the weight of multiple floors and the roof, and thus preventing collapse.
What to do when a building is collapsing?
In the event of a building collapse, it is imperative to remain on the floor and seek shelter under heavy furniture or doorframes. Remain calm and still, protecting your head and neck with your hands. Avoid contact with mirrors, door glasses, and safes. Do not utilize the elevator. Attempt to extinguish fires if possible.
What to do if trapped under collapsed building?
In the event of being trapped inside a collapsed structure, it is of the utmost importance to maintain composure and avoid any form of excessive vocalization in order to conserve strength. It is advisable to make noises by clapping or striking an object, and to listen carefully for any sounds that may indicate the presence of others. In such a situation, it is important to respond appropriately by making sounds that will help to establish contact.
How do you prevent a building from collapsing?
In order to prevent the collapse of buildings, it is essential to be aware of the standards that must be met in terms of construction area, to carry out inspections of the foundations, to avoid making significant changes, to construct buildings that are earthquake-proof, and to seek the assistance of professional structural engineers.
How to escape a collapsing building?
In order to guarantee a secure evacuation, it is advised that individuals position themselves in close proximity to the exterior walls of buildings or in external locations whenever feasible. By doing so, the probability of impeding one’s escape is diminished, as being nearer to the building’s outer limits increases the chance of having a clear and unobstructed exit route.

The bricks under the area where bricks were falling off were already missing bricks. You cant just hold up the rest of an unstable six story building with 2 or 3 leaning 2×4 sticks. This building had been showing major signs of deterioration for a long time, as shown in inspector reports and photographs over at least the past 3 years. The owner inexplicibly wanted to cut shoring (which holds up unstable parts of the building) out of the project to save money so he got rid of the first contractor who rightly refused to do the project without shoring and looked for a much cheaper bidder. It’s apparent they did next to nothing to hold up a building during repair work. The first contractor, who was working on another project nearby, even came by and warned the new contractor’s workers more than once, including on the morning of the day of the collapse, that the building was so obviously unstable that they needed to get away from it. No word on whether anyone bothered to tell the tenants.
The article, taken from the roof of a nearby building, shows what was happening before the building at 324 Main Street collapsed. The article cuts off as the building is collapsing; the person who owns the surveillance camera spoke to CNN on the condition of anonymity and explained it was because the power was knocked out during the collapse.
This parking area next to the hotel former hotel appears to me to have previously been occupied by what was probably a one story building or series of buildings that were torn down at some point which begs the question where did all these windows on the first floor come from that face the parking area. There wouldn’t be windows there if there was a building next-door, when were those holes cut in the wall? Were they done with a permit or are they done to code? They definitely weren’t done to code because unless they have horrible building codes there, with that major of an alteration, almost all building codes would require the entire building, be brought up to code which it obviously was not.
I worked as maintenance and housekeeping for them and lived in the davenport as I did..they wanted us to clean and fix each apartment as fast as possible and I did not agree with that..they paid us crap and ragged us about every little thing or if it wasn’t on time The manager was banging the maintenance guy and she was married…the owner never came around he had his dogs do everything. Also I saw bricks fall and seperate..when I raised concern they let me go..might wanna check the berg building next to it he owns that too along with the executive square.😂oh he sold it he prolly sold it right before he knew it was done for and got out.. really should go after the owner I worked for
January 31, 2020. – Russia, Saint Petersburg. – A view of the Saint Petersburg Sports and Concert Complex that has collapsed during demolition. The 29-year-old worker, who was identified as Matvey Kucherov, was later found in the rubble. He was one of four employees cutting metal cables atop the complex.
Among all the obvious and glaring safety issues, the severe lack of planning, the general lack of appreciation for what you are doing versus what can happen and the physical forces involved, the extreme negligence on the part of the safety department, and the lead engineers on this demolition project, I am amazed that both cranes survived the building collapse, and the only apparent casualties are the 2 workers on the roof, one by each man basket, cutting the beams that could be cut from the basket. This whole demolition of the inner roof was just haphazardly conceived and done. Looks like it was planned by some kid in 3rd grade. These workers died for no reason at all, except extreme stupidity and greed. Typical result, sadly.
So many people on here bashing this guy?? I agree there were bad decisions made. But… anyone who has done real work, and real dangerous work as I have done for many years, and like this poor guy was doing, knows that this type of thing could happen anytime to any worker. Use it to learn from and pray for his family who are left alone. But don’t make fun of him.
I am a structural engineer and the way I understand this collapse is that the roof of the structure was hanging from a circular beam. The were two reaction forces at the points where the circular roof was connected to the perimeter beam : Upwards reaction forces and out of the circle, like when you stretch a piece of cloth. Vertical forces at connection points were supported by the columns and horizontal forces were supported by the huge beam at the top. When all of these forces around the perimeter are combined, the outward forces balance and cancel each other out. But as he cuts the connection points one by one he releases the reaction forces one by one and increases the forces in points where the roof is still connected. This creates bending in the circular perimeter beam which it isn’t designed for and this causes the failure of the perimeter beam structure. All buildings should be studied well before coming up with a demolition plan and stages.
This may be the stupidest thing I’ve ever seen in any type of Construction Accident on YouTube!! While you really want to feel sorry for the guy that didn’t make it, how on earth do you not understand and realize what’s about to happen!!?? This structure pulls from every side to its center….with every disengagement of those contact points, tremendous energy is building up. It would be impossible for the outer platform where the workers are to not fall apart in a chain reactive release of energy!! This is just so sad to watch as even a little common sense applied would have prevented such a tragedy. Someone needed to sue somebody!!!
The cage was high mesh criss-cross. He had no chance of grabbing the side. Only the high top grab would work. – inaccessible basket entry design and selection – basket so far away; why? – no cable ties from person to basket for fall – no basic load distribution plan for demolition ($1,000 fee to any structural engineering firm for 3 hr consult) – no standard explosive demolition used – likely insufficient industry safety standards/promotion/culture or enforcement/penalties Cluster fuck of bad energies = failure.
Sad, very sad …. he panicked and instead ran away from the crane line holding the Torch tanks and tools that stayed floating, no safety cord …. feels like when a terrible event has taken away the floor underneath us …. or did he get contracted to do a one man demolition task in this domino action … comfort is one of our biggest deceptive feelings. Sad, he is or was a father, and the son of some unfortunate parents …. it could happen while a similar stadium is full with people.
What in Gods name were they thinking. This is why we have OSHA guidelines and policies in the U.S., I’m no engineer but I would have seen the danger in cutting that support bracing. You can’t suddenly release that kind of tonnage and NOT have a severe reaction. “For every action, there’s an equal and opposite reaction.” R.I.P. guys…
Definitely looks like something straight out of a movie or article game. Partially reminded me of the end of the first mission in call of duty 4 where you jump from the sinking ship to the evac chopper and get one of your first achievements on xbox called “Make the jump”. This dude certainly made one hell of an effort. That was absolutely catastrophic
This looks too much like CGI, like a scene from a movie, even the way the drone backs away just as the guy is perishing and pans to the building falling down. If the demolition company really cared enough to have a drone article recording this event, and they saw the guy miss grabbing the cage, they would have stayed focused on that most important part, and not zoomed out or panned to the collapsing colosseum. Plus it would make not sense to lift the cage up so high to keep the worker from getting into it, as the structure collapsed, since the cage could remain suspended indefinitely without the structure that was dropping away from beneath it. Watch it at 0.25 speed and you will see that the cage was lifted up higher for no reason before the structure fell down, leaving the worker stranded on it. All thinking people should have a healthy degree of skepticism about this and anything they see on Youtube purporting to be real, but looking surreal.
When what is called common sense SAFETY protocols are ignored. OSHA is always overbearing: IF this man had a safety line attached to the cage? He would have made. Annoying to wear? Maybe, but one hell of a lot less painful than dying PREVENTABLY. Not to mention family/friends who lost someone like this.
After perusal this li-terally more then a dozen times in slow motion you can see he not only reached the cage but hits it too. Unfortunately there may have not been something for his hands or fingers to claw or cling onto. You can see his right arm slide off the safety cage. Even worse if he was wearing gloves, I would imagine it’d be more difficult. He was 3 steps away, he only took 2 and jumped. I can’t imagine the coworker’s trauma, specially if he contemplates that if maybe he would’ve reached out his hand then perhaps they both could’ve made contact and maybe, save him…or maybe not. Certainly not the coworker’s fault OBVIOUSLY. I would freak tfo too and just hold on with both hands for dear life. Sad story 😞 Everything ive said you can see in the article.
the workers were without rescue equipment, even the one in the rescue cradle, without undergoing training. The director and foreman were sentenced to 2 years probation, not a real prison term!! but they are simply required to report to the police department every week AND THAT’S ALL! in fact no one is punished. Russia, Saint Petersburg. 2021
Look, I’m no genius okay… But when I pressed play on the article the first thing I thought was “thats a lot of weight that is slowly being redistributed asymmetrically. I hope those supports weren’t built in such a way where their strength comes from that tension… Followed by being instantly horrified. I mean… If I could have guessed the mode of failure, anyone could.
Is this real??! Oh my god if this is real this is AWESOME!!! perusal his final seconds as he scrambles to defy the inevitable is… Oh so sweet. He obviously didn’t think it through ir have anyone else smart enough with him to caution him against such a foolish action. And now he is no more. And nobody cares. Lol
I was in a hydraulic crane basket on the fly jib, the driver couldn’t jib up and looked confused. Took his time putting us down, he sucked in the jib we got out then the jib came down real fast to ground. Had to crane it onto the truck, cause the main rams were stuffed expanded by +5mm. We was lucky didn’t come down at full extension. same driver jibbed down to crane over tipped but he got load on ground – didnt go right over, he floated the crane 2 legs off ground often and had strained it.
Does anyone actually know if the “welder” died in this demolition? It appears that the the outer ring stays upright as the inside falls away. There is so much dust and debris that it’s hard to see if that piece falls, but I don’t see it collapse and I think it would fall straight back, which if it did, would exit the debris cloud. Obviously, there are many possibilities and not too many good ones, I’ve seen a article of a baby lying in a space on the train tracks with just enough space for this small human only, as the train passes over. Sometimes anything is possible
Well that’s certainly way to go out with style. That structural collapse was like something straight out of a James Bond flick. Except this really happened, and some guy lost his life as a result. His last panic striken moments as he desperately scrambled for safety in order to survive forever documented. R.I.P.
I don’t think you need to be an engineer to realise that that was a bad way to do this – the forces were mounting as each beam was cut. I would have thought explosive charges at strategic points going off together would have brought about the same effect (better, as symmetrical) without people putting their lives at risk. Not to mention the lack of even a harness.
While the roof clearly did not support the rim, the shift of weight and immense tension it created, when partially cut off, was obvious. Incredible how it was not predicted! The only way to demolish it was to start from the center, reducing the weight of the roof. Ore simultaneous explosions. – Cpt. Hindsight
Insane. The guy was working at height with not even the most basic risk assessment being carried out. Who was managing this job? What system in the world allows people to do that without a simple lanyard back to the crane? Truly bizzare anywhere but Russia which thinks nothing of massacring people. Hate to say that when a guy loses his life like that. But that country has so many lessons to learn.
😮 If it is true, as it seems to be, then someone is responsible for the death of these people. In the same way, when a gift was made to some armed states, then when it reciprocates with victims on the side of the one who gave the gift, then someone is responsible for the bad judgment of the recipient of the gift.😢
This is a scene worthy of darwin’s award, it’s the same classical cutting the branch you are sitting on. Only in this case the stadium you are standing on. It’s survivable though, man kind is that resistant, Man kind falls from a plain with a parachute that doesn’t open, yet survives it Man kind is tough
